Al adequate to extract all SC-19220 site essential oils in the min from the initial drop oftime varies dependingsome circumstances, an extraction as extraction gear and Extraction condensate [22,23]. In on numerous variables such time of a minimum of 120 min is necessary to observe the first drop of condensate. Hence, below time for you to extract pomelo peel plant material sample. To find out the proper extraction optimal circumstances (material mass 500 gthe yield of essentialof two.1 mL/min), 90and measured fromthe starting of important oil, and distillation rate oil was screened min was chosen as the optimal extraction time. steam distillation until the volume of essential oil becomes constant. From Figures two and three, it might be seen that the extraction efficiency obtained at their respective optimal circumstances reached its peak right after 100 min in the first drop of condensate. That is constant with previous outcomes that most Citrus necessary oils were exhaustively extracted following 60 min in the very first drop of condensate [22,23]. In some cases, an extraction time of at the very least 120 min is expected to observe the initial drop of condensate. As a result, below optimal situations (material mass 500 g and distillation rate of two.1 mL/min), 90 min was chosen because the optimal extraction time. 3.two. Optimization of Important Oils Extraction with RSM 3.2.1. Suitability on the Model To optimize the distillation conditions, preliminary experiments have been deemed depending on 3 components, like mass of material (g), steam flow rate (mL/min), and distillation time (min). Subsequent, the RSM system was applied to optimize the conditionsProcesses 2021, 9,9 ofaffecting the distillation of necessary oils from pomelo peel. Determined by the CCD, the quadratic model representing the partnership in between the 3 things was developed with 5 levels, as shown in Table two.Table 2.

The experimental outcomes of 20 experiments along with the predictions of Style Professional 11 software program are shown in Table three. The values in Table 3 show that the experimental values usually do not deviate in the predicted values. In addition, it could be observed that the concentration of vital oil obtained in experiment 17 was the highest (6.28 mL/100 g) with all the sample weight of 500 g, steam flow price of 2.1 mL/min, and extraction time 90 min.Table 3.
